Arsene Wenger may talk up this current Arsenal side, but they're not yet a patch on the Invincibles

Arsene Wenger came out with some interesting comments about his Arsenal team on Monday, insisting that potentially it is the most exciting of his 13-year tenure in North London. There is no doubt that this squad has exceptional quality, but to say it is richer in goalscoring potential than a side containing the likes of Henry, Bergkamp, Ljungberg and Pires is surely a step too far.

They certainly did not seem too exciting on Tuesday night, when they barely broke sweat against AZ Alkmaar in the Champions League, and once again their mental strength can legitimately be called into question after they turned inexplicably jittery in the closing stages and conceded a late equaliser. It was not a piercing blow like Liverpool's capitulation to Lyon, but it is mental strength that may prevent this current Arsenal team from reaching the heights of Wenger's best; the Invincibles of 2003-04.

This Arsenal incarnation may boast some wonderful players, such as Andrei Arshavin, Cesc Fabregas and Robin van Persie, but picking a composite team of the current side and the famous unbeaten line-up of five years ago, I can only find space for two of Wenger's current crop. Wenger may believe this squad could be his most exciting, but it is still some way from bettering his very best.

Goalkeeper - Jens Lehmann

Manuel Almunia may be nowhere near as limited as his detractors insist, but Lehmann wins this one hands down. The German may have been irritable, irritating and irrational but he was a superb keeper who proved his class again and again during his five-year stay at the club.

Right-back – Bacary Sagna

The French full-back enjoyed an impressive first season, followed by a slightly underwhelming one last term, but he is solid in defence and offers more going forward than Lauren did. However, Lauren did have a tasty right hook on him, which we haven't yet seen from Sagna. This was a very close-run thing.

Left-back – Ashley Cole

He will never be forgiven for the manner of his departure, but what is undeniable is that Cole is a brilliant left-back and was sensational for Wenger. Clichy is a fine player, too, and very much in the Cole mould, but he is prone to errors and lapses in concentration.

Centre-back – Sol Campbell

Another player to leave Arsenal under a cloud, yet Campbell was arguably one of Wenger's most important signings. A rock at the back until his final season, he was exactly what Arsenal needed to fill the void left by Adams and Keown. William Gallas is fitfully superb, but Campbell was consistently brilliant.

Centre-back – Kolo Toure

Thomas Vermaelen may be quickly becoming a fans' favourite at the Emirates, but he still has some way to go to usurp Toure in supporters' affections. The Ivorian was not quite the same since his bout of malaria in 2008, but when alongside Campbell he was fearsome, physical and very, very good.

Right midfield – Freddie Ljungberg

The Swede came out of relative obscurity with Halmstad in Sweden in 1998 to explode onto the scene at Highbury. Ljungberg's energy, vision and goalscoring touch added so much to the Arsenal midfield, and while Theo Walcott has potential, it is still to be fully realised.

Left midfield – Robert Pires

Not including the genius that is Andrei Arshavin is a very tough call, but Pires' contribution at Arsenal was simply phenomenal. After a poor first season, the Frenchman transformed himself into one of the best players in world football, and has deservedly been voted as Arsenal's sixth best player of all time by supporters, which says it all.

Central midfield – Patrick Vieira

Unquestionably one of the greatest players ever to grace the Premier League, Vieira was a collosus in midfield for Arsenal. His physicality, energy and sheer presence terrified opponents and infused his side with confidence. Alex Song is a coming force, but Vieira was king.

Central midfield – Cesc Fabregas

If Vieira was Arsenal's totem in 2004, Fabregas is it now. The Spaniard is one of the world's best players, and would stroll into most teams in world football. Gilberto Silva may have played an important role in midfield for the Invincibles, but excluding Fabregas would be unthinkable.

Forward – Dennis Bergkamp

Robin van Persie may be an artist, but Bergkamp is an old master who seemed to light up the Arsenal canvas every time he stepped on to the pitch. Bergkamp's vision was phenomenal, and his ability to do the unexpected added a creative edge to the Invincibles that made them the complete team. If you have any doubts, watch and salivate over this goal.

Forward – Thierry Henry

Henry's impact at Arsenal simply cannot be understated. Arguably the best player ever to play Premier League football, the Frenchman may have occasionally been a moody presence but he was unstoppable. Raw pace, power and poise, Henry had it all and no one in the current Arsenal team is even close to him.
